1. Please print the English in the picture
1. It is a simple siaphragm building-a building in which both windward and leeward loads are transmitted through the floor and roof diaphragms to the same MWFRS.2.The building is low rise-it has a mean roof height less than 60ft, and has a least horizontal dimension not less than the mean roof height .3. The builing is enclosed- and meets requirements for wind-borne debris protection, if applicable.4. The building is regular -has no unusual geometrical irregularity in spatial form. 5.The building is not classified as a flexible building-has a fundamental frequency greater than 1heartz(fundamental period less than 1 second).6. The building does not have response characteristics that create unusual loading(such as galloping or vortex shedding ) and is not sited in a location where unusal wind load effects might occur.7. The building has an approximately symmetrical cross section in each direction, and has a flat roof or a gable or hip roof with slope less than or equal to 45 degrees (12 in 12 pitch)8. The building is exempted from the torsional loas case of ACSE 7Figures 6-10 (per footnote 5, one-and two-story wood-frame construction is exempted), or the torsional load cases do not control design.
2.vortex shedding What does it mean? Vortex shedding refers to the divergence, detachment, and separation of vortices; The above results are from the example sentence of Kingsoft PowerWord: 1. Numerical study of bathymetry effect on vortex shedding. Numerical study on the influence of terrain and water depth on vortex ejection. 
>3. How is the phenomenon of wind shaking in super high-rise buildings generated? The wind induced sway of super high-rise buildings is mainly caused by wind pressure fluctuations and vortex shedding, and the building will suppress this sway through devices such as dampers. When strong winds pass around a building, alternating shedding vortices are generated on its back, creating periodic pressure differentials. This vortex shedding phenomenon is the main cause of the buildings lateral sway (perpendicular to the wind direction). At the same time, the intermittent wind itself can generate irregular thrust and suction, causing the building to vibrate in the downwind direction. To control shaking, contemporary super high-rise buildings commonly use tuned mass dampers (TMDs), such as the giant steel ball weighing 660 tons suspended inside Taipei 101 building, which counteracts building vibrations by swinging in the opposite direction. The Shanghai center Building is equipped with an eddy current pendulum damper, which uses the electromagnetic principle to dissipate energy. In addition, the design of the buildings exterior is also crucial, such as using rounded corners, tapered splits, or spiral shapes (such as the Guangzhou Tower) to disrupt the regular formation of vortices and reduce wind loads from the source. Although this shaking ensures structural safety within the allowable design range, excessive acceleration may affect the comfort of the occupant and cause dizziness. Therefore, wind resistant design is one of the core technologies in the construction of super high-rise buildings. 『SILVER Official Website SERVICE』
